Description

Technical Field

[0001] This utility model relates to the field of controller technology, specifically to a cross-key structure. Background Technology

[0002] In the field of traditional gamepads and controllers, the D-pad is a key component for user input commands, and its structure and performance directly affect the user's operating experience.

[0003] Existing D-pad designs mostly employ a "carbon-printed + conductive rubber" switch structure. While this structure achieves basic button functionality to some extent, its relatively slow response speed cannot meet the demands of modern games for fast and precise operation, especially in scenarios requiring high-frequency actions, such as fighting games and shooting games. This latency can directly impact a player's competitive performance, reducing the game's smoothness and enjoyment. Secondly, in terms of feel, due to the physical characteristics of the "carbon-printed + conductive rubber" structure, the buttons often lack sufficient feedback force and consistency during pressing and rebounding, resulting in a soft, vague feel and a lack of clear tactile feedback.

[0004] The above-mentioned defects urgently need to be addressed. Utility Model Content

[0005] To address the issues of low sensitivity and poor tactile feedback of existing "carbon-printed + conductive adhesive" cross-shaped buttons, making them unsuitable for applications requiring high-frequency operation, such as game controllers, this invention provides a new cross-shaped button structure.

[0006] The technical solution of this utility model is as follows:

[0007] A cross key structure includes a cross key bracket, a silicone component, and a circuit board, wherein the silicone component is disposed between the cross key bracket and the circuit board.

[0008] The cross key bracket is provided with multiple buttons, and the silicone part protrudes upward to form multiple pressing protrusions that correspond one-to-one with the buttons, and the pressing protrusions abut against the corresponding buttons;

[0009] The top of the circuit board is provided with a plurality of micro switches corresponding to the push protrusions, and the bottom of the silicone part is provided with a plurality of mounting slots corresponding to the silicone part, and the micro switches are disposed in the corresponding mounting slots.

[0010] According to the present invention based on the above solution, the bottom of the silicone component is provided with two pins, and the circuit board is provided with two corresponding first mounting holes, through which the two pins pass.

[0011] According to the above-described scheme of this utility model, the two pins are arranged diagonally.

[0012] According to the above-described solution, the present invention also includes a base, wherein a connecting post is formed by the upward protrusion of the base, a first connecting hole is provided on the circuit board, a second connecting hole is provided on the silicone part, and the connecting post passes through the first connecting hole and the second connecting hole in sequence to connect with the cross key bracket.

[0013] According to the present utility model with the above-described solution, the bottom of the cross key bracket protrudes downward to form a fastening part, the connecting column is provided with a fastening groove, and the fastening part is disposed in the fastening groove.

[0014] According to the above-described scheme of this utility model, the base is provided with a second mounting hole corresponding to each of the two pins, and the two pins pass through the corresponding second mounting hole.

[0015] According to the above-described solution, this utility model also includes a housing, in which a receiving groove is provided, and the buttons of the cross-key bracket are disposed in the receiving groove.

[0016] According to the present utility model with the above solution, a positioning post is provided in the receiving groove, and a positioning hole is provided in the middle of the button of the cross key bracket, and the positioning post is fastened to the positioning hole.

[0017] According to the above-described scheme of this utility model, the outer shell and the cross key bracket protrude from the front shell of the controller after the buttons are snapped together.

[0018] According to the present invention based on the above scheme, a pin header is provided at the bottom of the circuit board, and the pin header is connected to the main circuit board of the controller.

[0019] The advantages of this utility model based on the above solution are as follows:

[0020] In the aforementioned cross-shaped key structure, the top of the circuit board is equipped with multiple microswitches that correspond one-to-one with the pressing protrusions of the silicone component, and the bottom of the silicone component is equipped with multiple mounting slots that correspond one-to-one with the silicone component. The microswitches are installed in the corresponding mounting slots. The microswitches have the characteristic of fast response and can complete the switching action in a very short time, thereby improving the response speed of the cross-shaped key. Compared with the traditional "carbon printing + conductive glue" structure, the contacts of the microswitches are more stable, reducing the response delay caused by poor contact, and are more suitable for occasions where controller buttons require high-frequency operation.

[0021] In addition, the silicone parts protrude upwards to form pressing protrusions that correspond one-to-one with the buttons on the cross key bracket. The pressing protrusions abut against the corresponding buttons, and the silicone parts can improve the feel of the cross key. When the user presses a button, the silicone parts undergo elastic deformation, transmitting force to the micro switch. The shape of the silicone parts conforms to the shape of the micro switch, ensuring uniform force distribution and reducing the problem of inconsistent response caused by uneven force distribution, thereby improving the sensitivity of the cross key.

[0022] In addition, the micro switch on the circuit board is set in the mounting groove corresponding to the silicone component, that is, the silicone component is sleeved on the outside of the micro switch, which can prevent dust, dirt and other impurities from entering the inside of the micro switch, thereby extending the service life and stability of the micro switch.

[0043] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0044] like Figures 1 to 4 As shown, the present invention provides a cross key structure, including a cross key bracket 1, a silicone component 2, and a circuit board 3. The silicone component 2 is disposed between the cross key bracket 1 and the circuit board 3, forming a compact structure that not only saves space but also makes the entire cross key more stable, reducing the risk of failure caused by loosening or external impact.

[0045] like Figures 4 to 9As shown, in this embodiment, the cross key bracket 1 is provided with multiple buttons 11, and the silicone part 2 protrudes upward to form multiple pressing protrusions 21 corresponding to each button 11. The pressing protrusions 21 abut against the corresponding buttons 11. The top of the circuit board 3 is provided with multiple microswitches 31 corresponding to each pressing protrusion 21, and the bottom of the silicone part 2 is provided with multiple mounting grooves 22 corresponding to each silicone part 2. The microswitches 31 are disposed in the corresponding mounting grooves 22. The silicone part 2 can improve the feel of the cross key. When the user presses the button 11, the silicone part 2 undergoes elastic deformation, transmitting force to the microswitches 31. The shape of the silicone part 2 conforms to the shape of the microswitches 31, ensuring uniform force distribution and reducing the problem of inconsistent response caused by uneven force distribution, thereby improving the sensitivity of the cross key. Furthermore, the micro switch 31 features a fast response, completing the switching action in a very short time, thereby improving the response speed of the cross button. Compared to the traditional "carbon printing + conductive adhesive" structure, the contacts of the micro switch 31 are more stable, reducing response delays caused by poor contact, making it more suitable for applications where controller buttons require high-frequency operation. Additionally, the micro switch 31 on the circuit board 3 is positioned within the corresponding mounting slot 22 of the silicone component 2, meaning the silicone component 2 is fitted over the micro switch 31. This prevents dust, dirt, and other impurities from entering the micro switch 31, thus extending its lifespan and stability.

[0046] like Figure 8 , Figure 9 , Figure 10 As shown, in this embodiment, the silicone component 2 has two pins 23 on its bottom, and the circuit board 3 has two corresponding first mounting holes 32. The two pins 23 pass through the corresponding first mounting holes 32. Through the cooperation of the pins 23 and the mounting holes, the silicone component 2 can be quickly installed on the circuit board 3 without the need for additional fasteners (such as screws, nuts, etc.) or adhesives, greatly simplifying the installation process and improving production efficiency. In addition, when it is necessary to repair or replace the silicone component 2, the silicone component 2 can be easily removed from the circuit board 3 simply by pulling out the pins 23, simplifying the repair process and reducing repair costs.

[0047] like Figure 8 , Figure 9 As shown, in this embodiment, the two pins 23 at the bottom of the silicone component 2 are arranged diagonally. Compared to pins 23 arranged in a straight line, the diagonal arrangement is more resistant to forces from different directions, thereby enhancing the connection stability between the silicone component 2 and the circuit board 3. In addition, when subjected to external forces, the diagonally arranged pins 23 can more effectively disperse and resist torsional torque, reducing the risk of the silicone component 2 twisting or deforming due to uneven force.

[0048] like Figure 11As shown, in this embodiment, a pin header 33 is provided at the bottom of the circuit board 3. The pin header 33 is connected to the main circuit board of the controller (not shown in the figure). The connection between the pin header 33 and the main circuit board 3 adopts a plug-in design, which makes the assembly process faster and simpler. Compared with traditional connection methods such as soldering, the pin header 33 connection reduces assembly time and cost. When it is necessary to repair or replace the circuit board 3, the pin header 33 connection allows for quick disassembly and reinstallation, reducing maintenance difficulty and time costs.

[0049] In this embodiment, the cross key structure also includes a base 4, with a connecting post 41 protruding upwards from the base 4. A first connecting hole 34 is provided on the circuit board 3, and a second connecting hole 24 is provided on the silicone component 2. The connecting post 41 passes through the first connecting hole 34 and the second connecting hole 24 in sequence and connects to the cross key bracket 1, improving the overall stability of the cross key and reducing shaking or loosening during use. Specifically, a snap-fit ​​part 12 protrudes downwards from the bottom of the cross key bracket 1. A snap-fit ​​groove 42 is provided inside the connecting post 41 of the base 4. The snap-fit ​​part 12 is disposed within the snap-fit ​​groove 42, and abuts against the bottom of the groove, installing the silicone component 2 inside the cross key bracket 1. This increases the structural stability of the cross key, preventing the silicone component 2 from detaching from the microswitch 31 on the circuit board 3 and improving the response sensitivity of the button 11 on the cross key bracket 1. Furthermore, the abutment between the snap-fit ​​part 12 and the snap-fit ​​groove 42 reduces the gap between the cross key bracket 1 and the base 4, making the button 11 action more direct and rapid, thereby improving the response sensitivity of the button 11.

[0050] like Figure 12 As shown, in this embodiment, the base 4 is provided with second mounting holes 43 that correspond one-to-one with the two pins 23 on the bottom of the silicone part 2. The two pins 23 pass through the corresponding second mounting holes 43, thereby further mounting the silicone part 2 on the circuit board 3, enhancing the installation stability of the silicone part 2 on the circuit board 3, and reducing the risk of shaking or falling off during use.

[0051] like Figure 13As shown, in this embodiment, the cross key structure also includes a housing 5, within which a receiving groove 51 is provided. The button 11 of the cross key bracket 1 is disposed within the receiving groove 51. The housing 5 provides physical protection, preventing external impacts, dust, and dirt from damaging the internal components, extending the service life of the cross key, and maintaining its functional stability. Furthermore, the design of the receiving groove 51 ensures the precise positioning of the cross key bracket 1 and its button 11 within the housing 5, preventing component movement or misalignment during use, thereby ensuring operational accuracy and reliability. Additionally, a positioning post 52 is provided within the receiving groove 51, and a positioning hole 13 is provided in the center of the button 11 of the cross key bracket 1. The positioning post 52 is engaged with the positioning hole 13, providing a precise assembly position for the cross key bracket 1, ensuring that the button 11 of the cross key bracket 1 can be accurately placed within the receiving groove 51, avoiding misalignment or deviation during assembly. Meanwhile, the locating pin 52 and the locating hole 13 have a guiding effect, making the assembly process smoother and reducing assembly time and error rate.

[0052] like Figure 14 As shown, in this embodiment, the buttons 11 of the outer shell 5 and the cross-pad bracket 1 protrude from the controller's front shell 6 after being snapped together, making it easier for players to reach and operate the cross-pad bracket 1. Especially in fast-paced games or intense battles, this can significantly improve the accuracy and reaction speed of operation, ensuring that players can accurately locate the required buttons 11 during operation, thereby reducing operational errors caused by finger slippage or accidental touches.

[0053] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0054] The present utility model patent has been described above with reference to the accompanying drawings. Obviously, the implementation of the present utility model patent is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present utility model patent, or the direct application of the inventive concept and technical solution of the present utility model patent to other occasions without modification, are all within the protection scope of the present utility model.
